9 Claims.

This invention relates to metallic shingles and more particularly to animprovement in the inter-connecting features thereof, although certainfeatures thereof may be employed with equal advantage for otherpurposes.

It contemplates more especially the provision of an improved metallicshingle which has a novel inter-connecting means to preclude seepage orleakage of moisture therethrough for lodgment on a roof, and theaccomplishment of this effectual joinder with minimum requirements formaterial from which the shingle is constructed.

Numerous types of metallic shingles have heretofore been proposed, butthese have not proven entirely satisfactory because there is an unduerequirement for excess material in forming flanges and other connectingexpedients which do not prove especially efficacious in precludingleakage or moisture seepage therebetween. The requirement for theminimum utilization of material to cover a given area with effectualmeans to effect the joinder,I of adjacent shingles, constitutes animportant problem which has not thus far been successfully solvedwithout the provision of a shingle which is comparably expensive andless effectual. This is accomplished by the teachings of the instantinvention by the provision of effectual joining expedients on shinglesfor complemental attachment with adjacent shingles on the roof surfaceto preclude any possible drain or seepage thereon even though thejoinder thereof does not constitute a hermetically sealed connection.

One object of the present invention is to simplify the construction andimprove the facilities for joining adjacent metallic shingles.

Another object is to provide a metallic shingle having integral flangesconstituting improved connecting means precluding moisture seepage tothe building structure.

Still another object is to provide metallic shingles havinginter-connecting flanges which serve as a drain for any moisture to theexterior surface of the lower adjacent shingle.

A further object is to provide novel flanged connectors on metallicshingles without unduly increasing vthe material requirements therefor.

A still further object is to provide a novelly formed flangeconstituting a connector with complemental expedients provided onadjacent shingles as well as a drain for moisture that may seeptherebetween.

Still a further object is to provide a shingle having a novel connectingflange which precludes or at least reduces Amoisture Yseepage to aminimum and effects the drain thereof to the lower exterior surface ofthe lower adjacent shingle. Y

Other objects and advantages thereof will appear from the followingdescription of an i1- lustrative embodiment of the present invention.

The structure selected for illustration comprises a substantiallyrectangular sheet Ill of material composed of aluminum or othermaterials which is of desired gauge or thickness to meet commercialrequirements. The sheet I0 is provided with an elevated ridge I Iimpressed therein along the side edge I2 which terminates in a reverselybent flange I3 disposed beneath the sheet I in alignment with theupstanding ridge I thereof. As shown, the reversely bent flange I3serves to define the edge I2 and an edge Ill spaced therefrom so as toafford the telescopic reception of a complemental flange extendingtherebetween from an adjacent shingle. The reversely bent flange I3 hasa bracket l5 depending from the edge I4 thereof for exposed extensionupon the surface of the sheet I0. It is to be noted that the bracket I5is connected to the flange I3 by virtue of an upstanding arm I6 which isof triangular configuration to sustain the flange I3 in an inclineddirection for reasons which will appear more fully hereinafter.

The fiange I3 is provided with apertures Il to enable the attachment ofthe shingle I l) to the roof surface by resort to any suitable fastenerssuch as nails. The flange I3 extends from the top edge of the sheet I Ilfor a substantial distance downwardly just short of a lower edged flangeI8 provided therealong. The inclination of the roof attaching bracket I5imparts an inclination to the reversely bent flange I3 of a degreedepending largely upon the slope of the roof surface and this isutilized for the purpose of draining any moisture seepage that may findits way within the flange I3 between the edges I 2 and I4 thereof. 'Iothis end, the lower surface I9 of the flange I3 is depressed to define arunway 20 which guides the moisture along the edge of the sheet I0 fordeposit on the exterior surface of the lower adjacent shingle I0.

It is to be noted that the other edge 2| disposed parallel to the edgeI2 is provided with an opposite reversely bent flange 22 disposedbeneath the sheet Iii for telescopic engagement with the reversely bentflange I3. The flange 22 has a portion 23 thereof spaced from the sheetconnecting portion 24 for a distance sufficient to receive the edge I2together with its upraised portion I I. In fact, the flanged portion 23is spaced for a somewhat lesser distance so as to yield slightlyresponsive to its application over the edge I2 of the adjacent shingleto effect a hermetic joinder therebetween. With this arrangement,moisture seepage will practically be avoided or at least reduced to aminimum by virtue of the .upraised edge portion I I which precludesmoisture flow or entrance therearound. Should the lconnection besomewhat distorted or imperfect for any reason whatsoever, then themoisture will be collected in the runway 20 and thence drain to theexterior surface of the lower adjacent shingle as will presently appear.

As described supra, the lower edge of the shingle sheet I0 is providedwith a flange I8 turned therebeneath for engagement with an oppositelyhooked flange 25 constituting the top edge of the sheet I0. Inconsequence, the adjacent shingles I0 are provided with complementalflanges on all edges thereof for engagement and an edge shingle Ill isanchored or fastened to the roof surface by virtue of the bracket I5.Any suitableimpressions such as an upraised shoulder area 26 may beprovided in the shingle `sheet `I I) so as to impart a suitable designornamental appearance to the shingle surface when assembled in a mannermore clearly described in Figure 9. The adjacent shingles II! are firstanchored by means of a bracket I 5, and thence they are overlapped alongtheir sides for engagement to preclude moisture seepage and afford thedrain thereof should any occur by reason of imperfect joinder orvariations occurring before, during or after the placement thereof. Itwill be observed that minimum material is utilized in the attachinglbrackets and flanges so that the cost thereof is reduced to a minimumand an effective joinder between adjacent shingles rendered possiblewithout entailing any undue labor or time in the installation thereof.

In the modified embodiment disclosed in Figures 5 to 10 inclusive, theside -edged flanges I and 22' as well as the roof attaching bracket I5are utilized as in the previously described structure. In this instance,however, the bottom flange I8 is provided with a reversely bent flange21 which terminates in roof attaching brackets 28 for application to aroof surface along both the side and bottom edge for additonalinsurance. The top edged flange 25 is telescopically disposed betweenthe bottom edged vflange I8 and reversely bent extension 21 forengagement with the shoulder formed therein by virtue of a raised area3D impressed therein. Otherwise the structures are substantiallyidentical save for the additional bottom bracket 28 which is interruptedby a cut out portion 3| therebetween or along a vertical median line forrendering the top ange 2| of the lower adjacent shingle accessible fortelescopic engagement and disengagement.

It is thus apparent that the shingles I and/or 10 I 0' are protected onall sides by flanges that are complemental to adjacent edges ofsuccessively laid shingles. The arrangement of parts above describedaffords the laying of shingles IG and/or ID from the top ridge of a roofto the eaves there- 15 of. In other words7 the shingles I Il and/or I3are attached in horizontal alignment and interengagement along the ridgeof the roof. These are individually laid for independent attachment bydriving nails through the inclined flange I5 20 in shingle III andthrough both flanges I5 and 2d in shingle I0. Thereupon, the top flanges25 and 25 of the next lower tier or row of shingles are inter-engagedwith the lower edge flange I8 and I8' of the above tier just previouslylaid, 25 thereby affording top-down application of the shingles IUand/or I5. This coupled with complete inter-engagement along all edgeswith a special drain feature for all seepage, provides a novel,effective and comparably less expensive 30 shingle from a material andlabor standpoint.

Various changes may be made in the embodiment of the invention hereinspecifically described without departing from or sacrificing any of theadvantages of the invention as defined in 35 the appended claims.
